+1.1 Alpha value support for plotting in memory.
 
+The function plsmema() was added to the PLplot API. This allows the user
+to supply a RGBA formatted array that PLplot can use to do in memory
+plotting with alpha value support. At present only the memcairo device
+is capable of using RGBA formatted memory. The mem device, at least
+for the time being, only supports RGB formatted memory and will exit
